Title: Selected public health indicators by Chicago community area Brief Description: This dataset contains a selection of 27 indicators of public health significance by Chicago community area, with the most updated information available. The indicators are rates, percents, or other measures related to natality, mortality, infectious disease, lead poisoning, and economic status. Description: The table beginning on page 3 of this document provides the units for the measure, the United States baseline value of the measure and the years of data used to calculate it (US year), the Healthy People 2020 target, the value for the City of Chicago as a whole (City rate or %) and the years of data used to calculate it (City year). The Chicago Department of Public Health (CDPH) calculated the indicators using a variety of sources, including •

Geocoded annual birth and death certificate datasets supplied by the Illinois Department of Public Health (IDPH)



Census tract-level counts and estimates obtained from the U.S. Census Bureau 2000 census, 2010 census, and 2006-2010 American Community Survey



Case reports and laboratory reports received under the notifiable disease rules of the Illinois Administrative Code.

Most indicators are percents, crude rates, age-adjusted rates, or age-specific rates. A crude rate is the total number of events occurring among residents of a specified geographic area (e.g., community area, ZIP code) divided by the total population for the same geographic area, for a specified time period. An age-specific rate is the number of events occurring among residents within a particular age range in a specified geographic area divided by the total population within the same age range for the same geographic area for a specified time period. An age-adjusted rate is a rate that controls for the effects of differences in population age distributions. The age-adjusted rate is the weighted average of the age-specific rates observed in a population, with the weights derived from the age distribution of an external population standard, such as the U.S. 2000 standard population (see http://www.cdc.gov/nchs/data/statnt/statnt20.pdf). Different standard populations have different age distributions and the choice will affect the resulting age-adjusted rate. The indicators are point estimates that come from more comprehensive data tables that typically include years other than the most recent year, as well as additional information such as raw counts, alternative measures, and confidence intervals. The degree of uncertainty, or confidence that the indicator value is reflective of reality, varies for each measure and each community area. A confidence interval is a range of values used to describe the uncertainty around a measurement (e.g., the rate) and serves as a measure of the variability in the data. For brevity of presentation, the confidence intervals around each estimate have not been included in this dataset, but CDPH strongly recommends that confidence intervals to be considered when making comparisons; for more information, search the City of Chicago Open Data Portal for the table pertaining to the indicator of interest, or contact [email protected] for assistance.

These documents accompany the indicator-specific table on the City of Chicago Open Data Portal; for further assistance, contact [email protected]. Gonorrhea rates and confidence intervals are not included in the table for community areas in which fewer than 5 cases were reported in 2010. Confidence intervals are not shown for percents when the number of events used in their calculation was less than 5. Healthy People 2020 is a set of 10-year national objectives for improving the health of all Americans. Healthy People 2020 is comprised of approximately 600 objectives and over 1300 measures. Many of the objectives focus on interventions that are designed to reduce or eliminate illness, disability, and premature death among individuals and communities. Additional objectives are aimed to eliminate health disparities, address social determinants of health, improve access to quality health care, strengthen public health services, and improve the availability and dissemination of healthrelated information. For additional information on Healthy People 2020, see http://www.healthypeople.gov/2020/about/default.aspx. Disclaimers: IDPH specifically disclaims responsibility for any analysis, interpretations, or conclusions. The population counts and socioeconomic measures used in certain calculations are estimates, and this potential source of error should be taken into account when considering the precision of the indicators. Methods and data sources are not identical to those used in CDPH reports distributed prior to May 2012. Data owner: Epidemiology and Public Health Informatics, Chicago Department of Public Health. Time period: 2004 – 2010 Frequency: Updated as new data becomes available. Errata: The datasets originally posted to the Open Data Portal on June 1, 2012 for infant and causespecific mortality were revised on July 3, 2012. The dataset of selected public health indicators by Chicago community area was revised to reflect those corrections and uploaded on July 5, 2012.
